We examine the impact of geopolitical risk on the market value of aerospace and defense firms. We employ a global panel of 3,671 firm-year observations from 247 publicly listed firms across 30 countries during 1987–2024. We find that heightened GPR is positively associated with firm value and is channeled through higher military expenditure and firm-level revenues. We further show that this positive association between geopolitical risk and firm value holds during both geopolitical acts and geopolitical threats, with geopolitical threats providing more pronounced effects. Our results remain robust to alternative model specifications, different sample periods, and endogeneity tests. We offer important implications for investors, policymakers and lenders.

Purpose: In recent decades, accounting scholars have demonstrated a growing interest in studying charitable organizations. While prior qualitative reviews exist, there has been no quantitative and systematic review synthesizing accounting research in charities. This study aims to fill this gap by consolidating insights from diverse literature through a bibliometric analysis (BA) and systematic literature review (SLR). Design/methodology/approach: Based on a sample of 341 peer-reviewed articles from Scopus, this paper maps this research landscape through the adoption of a BA and SLR methodology. The analysis uncovers the most frequent types of charities, research methods and theories, displays the publication trends, and reveals their social and intellectual structure while identifying the research trends from 1982 to 2024. Findings: Social services and health organizations emerge as the most prevalent types of charities in accounting research. The analysis shows an upward publication and citation trend, characterized by a substantial contribution from high-quality journals and the influential role of the United States and the United Kingdom. Collaboration patterns reveal a network concentrated in Anglo-Saxon countries. Six clusters are identified and discussed in the classification of existing literature. Finally, the field's conceptual evolution illustrates emerging trends, particularly in the post-COVID-19 pandemic landscape, offering avenues for future research. Originality/value: This study presents a fresh perspective on accounting research in charities by combining SLR with BA. Covering nearly four decades of research, it maps the field's collaborative, intellectual and conceptual structure, reveals recent developments and outlines future directions for scholars and practitioners.

Purpose: This study aims to profile article retractions in accounting and finance (A&F) research and recommend best practices to mitigate academic misconduct or unintentional errors. To date, there is limited knowledge and understanding of research retractions in A&F. Design/methodology/approach: A profiling analysis examines retracted articles published in A&F journals in the 2021 Academic Journal Guide. Retracted publications from 2005 to 2023 are identified using the Retraction Watch database and journal websites. Bibliometric data from Scopus is utilized to analyze features related to these articles, while researchers’ characteristics are gathered from external sources, including university websites, Google Scholar, ResearchGate, LinkedIn, ORCID and Scopus. Findings: Evidence shows that, during the period under investigation, 95 articles published in 36 peer-reviewed A&F journals, authored by 161 scholars, were retracted. The primary reasons for retraction are data falsification, fake peer review and plagiarism. These authors are typically experienced, young males across all academic ranks, mainly affiliated with US and European universities. After the retraction, many authors changed academic institutions or left academia. Practical implications: The results of this study are expected to assist the A&F academic community in better understanding the nature and impact of article retraction, aiming to establish awareness and stronger mechanisms of monitoring, control and ethical policies over the publication process. Originality/value: To the best of our knowledge, this is the first study in A&F to provide a comprehensive analysis and insights on research infractions related to retractions. Research integrity in the A&F disciplines is of paramount importance since the research output disseminated is influential for the business and economic community.

This study examines how environmental, social, and governance practices impact firms' technical efficiency, focusing on operational capabilities often overlooked in financial performance measures. Using a nonparametric frontier analysis with robust order‐ m estimators, we analyzed 6033 firms across Asia from 2015 to 2022. Results show a nonlinear, “U”‐shaped relationship: initial environmental, social, and governance investments may decrease efficiency, but surpassing a threshold improves it. This suggests that while early environmental, social, and governance efforts may lead to inefficiency due to adjustments, long‐term benefits include better stakeholder investment and innovation. Firms also showed greater resilience during the COVID‐19 pandemic. The sector‐specific analysis supports this “U”‐shaped trend but highlights the need for detailed, sector‐specific research.

This article reviews the 25 years of Accounting History. Using bibliometric analysis, we provide a summary of bibliometric statistics to present an overview of the peer-reviewed journal's publication landscape. For this reason, we use a sample of 566 documents from the Scopus database between 1996 and 2021. We document publication and citation data indicating an increased rate of productivity and influence. We identify the leading authors, institutions and countries and find that most contributions stem from Australia-based affiliations. We also apply network analysis to reveal the major themes, collaboration patterns and existing relationships among topics. We discover that the journal displays global views that are not limited to the wisdom of one country. We classify dominant topics into 11 clusters and suggest promising avenues for future research.

This paper examines the time-varying spillover effects and connectedness between the euro and other EU and non-EU currencies after the end of the sovereign-debt crisis. We employ the Quantile Vector Autoregression connectedness approach using intraday data for seven currencies (the euro, the British pound, the Swiss franc, the Polish zloty, the Hungarian forint, the Czech koruna, and the Norwegian krone) spanning from 1 January 2016 to 30 November 2022. The results indicate that, almost in all quantiles, the currencies of Eastern European Group countries (i.e., Czech Republic, Hungary, and Poland) are net contributors of information spillovers to other currencies, while currencies of non-EU countries (Switzerland, UK, and Norway) are net takers. Further, we find that the euro is the highest transmitter of net information spillovers to all other currencies until 2021. Interestingly, after 2021, the euro changes to net information spillover taker from all other currencies; highlighting that external shocks (e.g., COVID-19, the energy crisis) have significant risk spillover effects on the European currency market. Policymakers and market participants could benefit from knowing which currency drives developments to avoid unexpected consequences.

Purpose: Sustainable development (SD) is becoming an important area of research in accounting education. This paper examines if postgraduate accounting students in the Greek context present different awareness of SD issues and if this is related to their Master’s orientation. Moreover, it compares the results with other similar studies.Design/methodology/approach: An online questionnaire was designed based on Ebaid (2022) and Aleixo et al. (2021), and distributed to two different Master’s orientation programs. Then, descriptive statistics and contingency table analysis were performed to illustrate the main differences regarding the students’ responses.Findings: The results indicate that the examined postgraduate students recognize the importance of SD for their future careers and require more knowledge about this issue. Moreover, it is presented that most of the postgraduate students adhere to the core sustainability principles (i.e. recycle, reuse and reduce), while only the students of environmental, social and governance (ESG) Master are significantly and actively engaged in social and environmental activities. Collectively, the results show that postgraduate students in Greece are more familiar with the term SD compared to participants in other similar studies in different contexts.Practical implications: Planners and decision-makers in higher education institutions could benefit from the findings to reconsider accounting education by introducing new courses and/or Master’s programs to promote knowledge and action for SD.Originality/value: This is the first study, as far as we know, that examines the issue of sustainability and accounting education on postgraduate students.
